This is automatically regenerated at hourly intervals to include updates from the NEOCP (Near-Earth Object Confirmation Page). Click on the designation for any object to get a pseudo-MPEC for it. Uncertainties in orbital elements will almost always be given.
To be done: Provide advice on which object(s) are most in need of follow-up. This will take into account factors such as: is the uncertainty more than a few arcseconds, but low enough to make it possible to find the object? Is the uncertainty within reason, but about to grow to a point where the object will be hard to find? Is the object about to get really faint? Is a close approach/impact imminent? Does it have weird/interesting orbital elements? Is this a possible radar or ARRM target?
Also, source code for all this needs to be posted, and (I hope) this system run on other servers as a backup plan.
Note: 'Sig1' = current ephemeris uncertainty; 'Sig2' = ephemeris uncertainty in two days. This is a good guide as to how important it is to get a particular object. If the current uncertainty is ten arcseconds, but it'll be twenty degrees in two days, you'd best get it soon. If it'll only have grown to an arcminute, it may not be so important. (Though it's only a guide. The object may get faint or close to the sun or too far south or north for you during those two days. Which is why my work here is not yet done.)
